This functions read the data value of the specified attribute(s) of an defined EDMprotectedData instance. The first 5 arguments are mandatory, the rest are optional. For each attribute to retrieve the value of, the 3 arguments "attributeNameOrAttributeId", "attributeReadCondition", and "attributeValue" must be specified. The "attributeReadCondition" can be specified as INDETERMINATE (?). The actual EDMprotectedData must have been defined with xpxREAD_ACCESS in the related xpxDefineProtectedData() operation, and the optional defined "readCondition" must be evaluated to TRUE before this operation can be successfully performed. The "readCondion" argument must evaluate to TRUE before this operation can be successfully performed. For each attribute to read the actual attribute must have been defined with xpxREAD_ACCESS, the optional defined "attributeCondition" must be evaluated to TRUE, and the optional "attributeReadCondition" argument must be evaluated to TRUE, before the actual attribute read operation can be successfully performed.
